A commercial jetliner is a type of aircraft designed to transport passengers and cargo over long distances. These planes are typically larger than private jets and can carry hundreds of passengers at once. They are powered by jet engines, which allow them to fly at high altitudes and speeds, making air travel efficient and convenient. Major manufacturers of commercial jetliners include companies like Boeing and Airbus. Commercial jetliners are used by airlines around the world to connect cities and countries. They operate on scheduled flights, providing a vital service for business and leisure travelers. Safety regulations and maintenance standards are strictly enforced to ensure the well-being of passengers during flights.
